MARKING-TOOL FOR LAT H ES.

SPECIFICATION forming part of Letters Patent No. 461,966, dated October 27, 1891.

Application filed April 21, 1891. Serial No. 389,744. (No model.)

To all whom it may concern.-

Be itknown that we, MORRIS TANNENBAUM and MICHAEL GOTTDINER, both of New York city, New York, have'invented an Improved Marking-Tool for Lathes, of which the following is a specification.

This invention relates to a tool adapted to be held against the work in a wood-turners lathe, so as to mark the work at the points where the cutters are to be applied. The tool being first set is ready to mark rapidly and in a uniform manner all the work that is to be turned out 011 the same pattern.

The invention consists in the various features of improvement more fully pointed out in the claim.

In the accompanying drawings, Figure 1 is a face View of our improved marking-tool. Fig. 2 is a cross-section on line a: m, Fig. 1.

The letter (1 represents a slotted bar, and b b are a number of slides clamped to the bar by means of winged nuts I), that engage screwposts 6, secured to the slides. The slides b are provided with shoulders 12 at the front and rear to insure a proper position and a rectilinear motion. Each slide is doublepointed, the forward point b constituting a marking-tool, while the diametrically-opposite rear point b constitutes an index-finger. The screw post 6 projects upward from the face of the slide midway between the points If b as shown.

To the two ends of the bar a there are attached a pair of handles 0, to which in turn there is secured a graduated rod or scale d,

parallel to bar a and along which the fingers 19 move.

In use the slides 12 are set to the desired pattern by means of the scale cl, and then the tool is by the handles 0 held against the work 0 formed 011 the same pattern may be rapidly marked, after which the slides 79 are changed to a new pattern.

What We claim is The combination of bar a with slides I), having points 19 b diametrically opposite each 5:)

other, screw-post e, projecting upwardly from the face of the slide, a winged nut engaging the screw-post, and with a scale d and handle a, substantially as specified.
